NAME 
config/gen/opengl.pm - OpenGL binding generated files
DESCRIPTION
Generates several files used by the OpenGL binding. These include:
NAME
$C_FILE - GLUT Callback Function Handling
DESCRIPTION
GLUT callbacks are always synchronous and have void return type. None of them accept user data parameters, so normal Parrot callback handling cannot be used.
Functions
void glutcbTimerFunc(PARROT_INTERP, sub, milliseconds, data)- Register a Sub PMC to handle GLUT Timer callbacks.
void glutcbJoystickFunc(PARROT_INTERP, sub, pollinterval)- Register a Sub PMC to handle GLUT Joystick callbacks.
void $_-{glutcb}(PARROT_INTERP, sub)>- Register a Sub PMC to handle GLUT $_->{friendly} callbacks.
